In staRdom: PARAFAC Analysis of EEMs from DOM

Add layers of scatter bands, molecular regions and common peaks to EEM plots

Description

This function is a wrapper for geom_eemregions, geom_eempeakloc, geom_eemscatter and can limit the plot extend to the area of the original EEM. Therefore, it is not added using '+' but the plot has to be supplied as an argument.

Usage

ggeem_overlay(
  plot,
  scatter = rep(TRUE, 4),
  regions = TRUE,
  peakloc = TRUE,
  limit = TRUE,
  ...
)

Arguments

plot	the ggplot where the layers are added
scatter	logical vector of size 4 stating the scatter bands to be marked. The order is Raman 1, Raman 2, Rayleigh 1, Rayleigh 2.
regions	logical, whether molecular regions are marked
peakloc	logical, whether common EEM peaks are marked
limit	logical, whether the plot is limited to the original EEM
...	additional arguments passed to geom_eemregions(), geom_eemscatter() and geom_eempeakloc().

Value

an altered ggplot2

Examples

require(tidyr)

eem_list %>%
 eem_extract(eem_names((eem_list))[1], keep = TRUE) %>%
 ggeem() %>%
 ggeem_overlay()
